The award was created by Robert Schmunk, Evelyn Leeper, and Steven H Silver, all of whom are still judges. Over the years, the number of judges has increased to eight, including judges in the United Kingdom and South Africa.
Each year, two awards are presented at Worldcon. The Short Form award is presented to a work under 60,000 words in length. The Long Form award may be presented to a work longer than 60,000 words, including both novels or complete series. At their discretion, the Sidewise Award judges (a panel of eight) may elect to recognize an individual or work with a Special Achievement Award. The Special Achievement Awards recognize works that were published prior to the award's inception.
Harry Turtledove has been nominated several times and has won thrice. In addition two stories which appeared in anthologies edited by Turtledove have been nominated for the award, one of which has won.
